Technical Impacts of DNS Privacy and Security on Network Service Scenarios
- Technical Impacts of DNS Privacy and Security on Network Service Scenarios ATIS-I-0000079 | April 2020 Abstract The domain name system (DNS) is a key network function used to resolve domain names (e.g., atis.org) into routable addresses and other data. Most DNS signalling today is sent using protocols that do not support security provisions (e.g., cryptographic confidentiality protection and integrity protection). This may create privacy and security risks for users due to on-path nodes being able to read or modify DNS signalling. In response to these concerns, particularly for DNS privacy, new protocols have been specified that implement cryptographic DNS security. Support for these protocols is being rapidly introduced in client software (particularly web browsers) and in some DNS servers. The implementation of DNS security protocols can have a range of positive benefits, but it can also conflict with important network services that are currently widely implemented based on DNS. These services include techniques to mitigate malware and to fulfill legal obligations placed on network operators. This report describes the technical impacts of DNS security protocols in a range of network scenarios. This analysis is used to derive recommendations for deploying DNS security protocols and for further industry collaboration. The aim of these recommendations is to maximize the benefits of DNS security support while reducing problem areas. Foreword As a leading technology and solutions development organization, the Alliance for Telecommunications Industry Solutions (ATIS) brings together the top global ICT companies to advance the industry’s business priorities. ATIS’ 150 member companies are currently working to address network reliability, 5G, robocall mitigation, smart cities, artificial intelligence-enabled networks, distributed ledger/blockchain technology, cybersecurity, IoT, emergency services, quality of service, billing support, operations and much more. -
Lab 3: Scanning and Reconnaissance
CSC 5991 Cyber Security Practice Lab 3: Scanning and Reconnaissance Introduction The key to successfully exploit or intrude a remote system is about the information you have. The first step for penetration is the scanning and reconnaissance. In this lab, you will learn how to use tools to scan and retrieve information from a targeting system. You will be using nmap and OpenVAS to scan a vulnerable machine and identify exploits that can be used to attack it. We will use two Linux virtual machines: One is a Kali Linux with nmap and OpenVAS installed; and the other one is intentionally vulnerable Linux. We will use the nmap and OpenVAS on Kali Linux to scan the vulnerable Linux machine. Software Requirements - The VMWare Software http://apps.eng.wayne.edu/MPStudents/Dreamspark.aspx - The Kali Linux, Penetration Testing Distribution https://www.kali.org/downloads/ - Metasploitable2: Vulnerable Linux Platform http://sourceforge.net/projects/metasploitable/files/Metasploitable2/ - nmap: the Network Mapper - Free Security Scanner https://nmap.org/ - OpenVAS: Open Vulnerability Assessment System http://www.openvas.org/index.html Fengwei Zhang - CSC 5991 Cyber Security Practice 1 Starting the Lab 3 Virtual Machines We need to use two VMs for this lab: the Kali Linux and the Metasploitable2-Linux. First, select the Kali Linux and press Start up Login the Kali Linux with username root, and password [TBA in the class]. Below is the screen snapshot after login. Fengwei Zhang - CSC 5991 Cyber Security Practice 2 Then, you select Metasploitble2-Linux, and press Start up. This is an intentionally vulnerable Linux VM that you will attack against. -

Metasploit Pro User Guide
4.11 USER GUIDE Getting Started First things first. If you haven't installed Metasploit yet, check out this these instructions if you're a commercial user. Otherwise, if you already have Metasploit installed, congratulations! You've come to the right place to get started. What's Metasploit? Metasploit is a penetration testing platform that enables you to find, exploit, and validate vulnerabilities. The platform includes the Metasploit Framework and its commercial counterparts: Metasploit Pro, Express, Community, and Nexpose Ultimate. Metasploit Framework The Metasploit Framework is the foundation on which the commercial products are built. It is an open source project that provides the infrastructure, content, and tools to perform penetration tests and extensive security auditing. Thanks to the open source community and Rapid7's own hard working content team, new modules are added on a regular basis, which means that the latest exploit is available to you as soon as it's published. There are quite a few resources available online to help you learn how to use the Metasploit Framework; however, we highly recommend that you take a look at the Metasploit Framework Wiki, which is maintained by Rapid7's content team, to ensure that you have the most up to date information available. You can also use the sidebar navigation on the left to view the documentation that is available on this site; just click on the Metasploit Framework topic or search for the topic you want. Either way, if you are unable to find what you need, let us know, and we will add it to the documentation back log. -
List of NMAP Scripts Use with the Nmap –Script Option
List of NMAP Scripts Use with the nmap –script option Retrieves information from a listening acarsd daemon. Acarsd decodes ACARS (Aircraft Communication Addressing and Reporting System) data in real time. The information retrieved acarsd-info by this script includes the daemon version, API version, administrator e-mail address and listening frequency. Shows extra information about IPv6 addresses, such as address-info embedded MAC or IPv4 addresses when available. Performs password guessing against Apple Filing Protocol afp-brute (AFP). Attempts to get useful information about files from AFP afp-ls volumes. The output is intended to resemble the output of ls. Detects the Mac OS X AFP directory traversal vulnerability, afp-path-vuln CVE-2010-0533. Shows AFP server information. This information includes the server's hostname, IPv4 and IPv6 addresses, and hardware type afp-serverinfo (for example Macmini or MacBookPro). Shows AFP shares and ACLs. afp-showmount Retrieves the authentication scheme and realm of an AJP service ajp-auth (Apache JServ Protocol) that requires authentication. Performs brute force passwords auditing against the Apache JServ protocol. The Apache JServ Protocol is commonly used by ajp-brute web servers to communicate with back-end Java application server containers. Performs a HEAD or GET request against either the root directory or any optional directory of an Apache JServ Protocol ajp-headers server and returns the server response headers. Discovers which options are supported by the AJP (Apache JServ Protocol) server by sending an OPTIONS request and lists ajp-methods potentially risky methods. ajp-request Requests a URI over the Apache JServ Protocol and displays the result (or stores it in a file). -

Project 3: Networking Due: Parts 1–3: May 18 11:59 PM PT Part 4: May 25 11:59 PM PT
CS155: Computer Security Spring 2021 Project 3: Networking Due: Parts 1{3: May 18 11:59 PM PT Part 4: May 25 11:59 PM PT Introduction This project is all about network security. You will both use existing software to examine remote machines and local traffic as well as play the part of a powerful network attacker. Parts one and two show you how a simple port scan can reveal a large amount of information about a remote server, as well as teach you how to use Wireshark to closely monitor and understand network traffic observable by your machine. Part three will focus on a dump of network traffic in a local network, and will teach you how to identify different types of anomalies. Finally, in part four, you will get to implement a DNS spoofer that hijacks a HTTP connection. This project will solidify your understanding of the mechanics and shortfalls of the DNS and HTTP protocols. Go Language. This project will be implemented in Go, a programming language most of you have not used before. As such, part of this project will be spent learning how to use Go. Why? As you saw in Project 1, C and C++ are riddled with memory safety pitfalls, especially when it comes to writing network code. It's practically impossible to write perfectly secure C/C++ code|even experienced programmers make errors. For example, just this week, Qualys uncovered 21 exploits in Exim, a popular open source mail server. The security community has largely agreed that future systems need to be built in safe languages. -
